Where Venture Capital Went 2021–2023: The $600 Billion Peak, Crypto, Climate and the Reset

Venture capital investment by sector from 2021 to 2023 covers the most violent three-year swing the asset class has seen: a $600 billion-plus peak, a rate-driven reset and a trough in which only one sector kept growing. This article lays out, year by year, how much was invested globally and in the US, which sectors took the money, how the stage mix and valuations moved and what the generative-AI wave of 2023 set in motion. It is the second chronological instalment in the Sectors & Exits by Year pillar of the Kurums Venture Capital hub; the build-up is in our 2015–2020 review and the AI-dominated present is in where venture capital went in 2024–2026.

How much venture capital was invested globally in 2021, 2022 and 2023?

Global venture funding reached roughly $640–680 billion in 2021, fell to about $445 billion in 2022 and about $285–305 billion in 2023, according to Crunchbase; US deal value went from $354.6 billion to $238.2 billion to $162.2 billion over the same years (PitchBook-NVCA).

The spread in the 2021 figure reflects data revisions: Crunchbase’s January 2022 tally was $681 billion, while its later restated series puts the year closer to $643 billion as late-reported rounds were reclassified. PitchBook’s global series shows the same shape with a slightly lower 2021 total. Whichever provider you use, 2021 was more than double 2020 and roughly four times 2016, and it was driven by round size rather than company count: billion-dollar rounds and $100 million-plus “mega-rounds” accounted for well over half of the dollars.

The US restated series from the PitchBook-NVCA Venture Monitor is the most reliable guide to magnitude. Deal value of $354.6 billion in 2021 came on 19,373 deals; 2022’s $238.2 billion on 18,027 deals shows that deal counts held up for a year while sizes shrank; 2023’s $162.2 billion on 14,712 deals is the point at which activity itself contracted. Exit value tells the harsher story: $841.5 billion in 2021, $148.0 billion in 2022 and about $120 billion in 2023. Those exit numbers are examined deal by deal in our year-by-year table of the largest venture-backed exits.

Which sectors won the 2021 record year?

Fintech was the largest single sector in 2021 at roughly $130 billion globally (CB Insights), followed by healthcare and biotech, enterprise SaaS, crypto/web3 at about $30 billion, and climate tech, which passed $40 billion for the first time.

Fintech’s year was extraordinary by any measure. CB Insights counted more than $130 billion across about 4,900 deals, more than double 2020, with Klarna raising at $45.6 billion, Stripe at $95 billion, Revolut at $33 billion, Nubank ahead of its December IPO, and a long tail of neobanks, BNPL providers, payments infrastructure and insurtech. Crypto and web3 went from a niche to a mainstream venture category: PitchBook and Crunchbase both put 2021 crypto venture funding near $30 billion, with FTX, Celsius, Sorare, Dapper Labs and OpenSea raising at multi-billion valuations and a16z closing a $2.2 billion crypto fund in June. Enterprise SaaS continued to absorb the most deals by count, and the IPOs of UiPath, Confluent, HashiCorp, GitLab and Samsara made it the deepest exit pool.

Climate tech crossed into the mainstream, with PwC estimating well over $40 billion of 2021 investment in EVs, batteries, grid software, carbon accounting and alternative proteins; Rivian’s November IPO at a valuation above $70 billion was the most visible result. Healthcare and biotech raised a record (Rock Health counted $29 billion in US digital health alone), and consumer categories briefly came back: delivery (Gorillas, Getir, Gopuff), creator economy and gaming all raised heavily. The money came from crossover and non-traditional investors: Tiger Global alone led or co-led hundreds of rounds, SoftBank’s Vision Fund 2 deployed at pace, and hedge funds, sovereign funds and mutual funds participated in a majority of late-stage dollars.

Where the 2021 capital was concentrated

The top of the market dominated. In the US, rounds of $100 million or more accounted for well over half of deal value, late-stage share rose above 65% and the number of new unicorns worldwide exceeded 500 in a single year (Crunchbase and CB Insights both counted more than 500). At the same time seed and Series A round sizes rose sharply, which is why the subsequent down cycle hit both ends of the market, as described in our analysis of the venture barbell effect.

What did the 2022 rate shock do to sectors and valuations?

The 2022 shock hit sectors in order of their duration: crypto and consumer fell first and hardest, late-stage SaaS and fintech saw valuation marks cut by half or more, while early-stage, biotech and climate held up best; global funding fell about 35% to roughly $445 billion.

The timing is visible in Crunchbase’s halves: about $285 billion was invested in the first half of 2022 and roughly $160 billion in the second, with Q4 2022 the weakest quarter since early 2020. The trigger was monetary. The US Federal Reserve raised rates from near zero to above 4% during the year, public software multiples compressed from 15–20x revenue to 5–7x, and the Nasdaq fell about a third. Crossover investors, who marked to public comparables, withdrew almost immediately; Tiger Global and SoftBank wrote down tens of billions, and the mega-round count collapsed.

Crypto was the sector that broke. The Terra/Luna collapse in May, Celsius and Three Arrows in June and FTX’s bankruptcy in November turned 2021’s $30 billion category into a reputational liability; Crunchbase recorded web3 funding falling about 73% the following year. Consumer delivery and “quick commerce” (Gorillas, Getir, Zapp) ran out of road as subsidies ended. Fintech funding roughly halved, with Klarna’s July 2022 down round at $6.7 billion, an 85% cut from its 2021 mark, the defining data point. Layoffs tracked by Layoffs.fyi exceeded 160,000 tech employees in 2022.

Sectors with structural tailwinds held up better. Climate tech funding was roughly flat in 2022 as the US Inflation Reduction Act (August 2022) created subsidies for batteries, hydrogen, carbon capture and clean manufacturing; biotech fell but from a record; defence and space began attracting capital after Russia’s invasion of Ukraine; and early-stage rounds held their size for most of the year because seed funds had raised record capital in 2021–2022 (US VC fundraising actually peaked in 2022 at $188.5 billion). Term-sheet discipline returned, and founders rediscovered liquidation preferences and structure, which is why reading the term sheet before it reads you became essential again.

Why was 2023 the trough, and what did the layoffs and down rounds look like?

2023 was the bottom: global funding fell about 38% to roughly $285 billion (Crunchbase), US deal value dropped to $162.2 billion, venture fundraising halved, exits were at a decade low and more than 260,000 tech employees were laid off, per Layoffs.fyi.

The year began with the collapse of Silicon Valley Bank in March, which briefly threatened the operating accounts of thousands of start-ups and pushed CFOs to diversify banking relationships. Rates kept rising into the summer, the IPO window stayed shut for the first eight months (Arm, Instacart and Klaviyo tested it in September to mixed results) and LPs, short of distributions, cut new commitments. US venture fundraising fell to $97.5 billion from $188.5 billion, and global fund commitments dropped to about $160 billion, roughly $200 billion below 2021 (PitchBook).

Valuation compression showed up in the data with a lag. Carta reported that the share of US venture rounds that were down rounds rose from under 10% in 2021 to roughly 20% by 2023, and that bridge and extension rounds became the most common type of financing for 2021-vintage companies. Median late-stage pre-money valuations fell by about half from their 2021 peak. Structured terms (participating preferred, ratchets, 1.5–2x liquidation preferences) returned in growth rounds, and secondary buyers quoted discounts of 40–60% to last-round price for most unicorns, which is why tender offers and secondaries became a mainstream exit path, as covered in our guide to exit routes.

Sector by sector, fintech and web3 fell furthest, consumer and delivery almost disappeared from the mega-round list, and digital health funding fell to its lowest level since 2019. Climate tech was resilient rather than growing; the IRA kept battery, hydrogen and grid projects funded even as venture totals fell. Biotech bifurcated between well-capitalised platform companies and a long tail that could not raise. Defence tech kept growing from a small base, with Anduril’s $1.5 billion round at $8.5 billion in late 2022 and Helsing’s rounds in Europe the leading examples.

How did generative AI become the first wave of 2023?

Generative AI absorbed close to $50 billion in 2023 (Crunchbase), the only major sector to grow, with OpenAI’s $10 billion from Microsoft, Anthropic’s up to $4 billion from Amazon and $2 billion commitment from Google, Inflection’s $1.3 billion and Mistral’s €105 million seed and €385 million Series A.

ChatGPT’s launch in November 2022 changed the sector allocation of venture capital within a single quarter. Microsoft’s January 2023 investment in OpenAI, reported at about $10 billion, was the largest deal of the year and set the template for strategic investors providing compute credits alongside cash. Amazon’s September commitment of up to $4 billion to Anthropic and Google’s subsequent agreement to invest up to $2 billion made the foundation-model layer the first venture category financed primarily by hyperscalers rather than venture funds. Inflection AI raised $1.3 billion in June from Microsoft, Nvidia, Reid Hoffman and Bill Gates; Databricks bought MosaicML for about $1.3 billion; Hugging Face raised $235 million at $4.5 billion; and in Europe, Mistral AI went from a seed round of €105 million in June to a €385 million Series A in December, valuing a six-month-old company at about €2 billion.

Beneath the foundation-model layer, the AI infrastructure stack (CoreWeave, Lambda, Together, Pinecone, Weights & Biases) and the first application companies (Jasper, Harvey, Glean, Character.AI, Runway) raised the largest early-stage rounds of the year. Nvidia became an active venture investor. For founders outside AI, 2023 was the first year in which a sector premium of this size existed, and that gap has widened since; our guide to raising venture capital outside AI describes the practical consequences.

The 2023 numbers were still small relative to what followed. Crunchbase counted roughly $50 billion into AI in 2023 (about 17% of the global total), rising to more than $100 billion in 2024 and about $202 billion in 2025, which is the story told in our 2024–2026 review.

How did the stage mix change between 2021 and 2023?

Late-stage dollars fell fastest, from more than 65% of US deal value in 2021 to under 55% in 2023, while seed and early-stage deal counts held up better because seed funds had raised record capital; by 2023 bridge and extension rounds were the most common financing type.

In 2021 the stage pyramid was inverted: a small number of late-stage and growth rounds carried the majority of dollars, and crossover investors supplied most of them. When those investors left in 2022, late-stage deal value collapsed by more than half within twelve months while early-stage value fell by about a quarter. Seed proved the most resilient stage by count, partly because the record 2021–2022 fund vintages (US VC fundraising of $176.2 billion and $188.5 billion) had to be deployed, and partly because seed valuations had further to fall before investors balked.

By 2023 the picture had become the “bridge economy”. Carta data show more than 40% of Series A and B financings in 2023 were extensions or bridges on existing terms, and the median time between rounds stretched from about 18 months to more than two years. Growth-stage companies deferred rounds entirely by cutting burn, which is why layoffs peaked in Q1 2023, and many used venture debt or structured rounds instead of priced equity. The practical result was a two-year backlog of companies needing priced rounds that would only clear in 2024–2025, mostly in AI.

Which regions and investor types drove the swing?

The US accounted for roughly half of global funding throughout, Asia’s share fell as China tightened regulation and US outbound-investment rules took shape, Europe held its share, and the investor mix shifted from crossover funds and SoftBank in 2021 to hyperscalers and Nvidia by 2023.

China’s 2021 crackdown on education, fintech and platform companies, followed by Didi’s forced delisting, cut Chinese venture activity sharply from the second half of 2021, and the shift from USD to RMB funds accelerated. India had a record 2021 (over $35 billion) and then fell by more than half by 2023. Europe’s 2021 total exceeded $100 billion on Dealroom’s count and roughly halved by 2023, but the continent’s share of global funding was stable at 15–20%, helped by deep-tech, climate and the arrival of Mistral and Helsing. The Gulf emerged as a source of LP capital for Western funds and as a destination for growth rounds.

Investor types changed too. In 2021 the marginal dollar came from Tiger Global, Coatue, SoftBank, D1 and mutual funds; in 2023 it came from Microsoft, Amazon, Google, Nvidia and sovereign funds, almost entirely into AI. Traditional venture firms responded by raising large multi-stage funds in 2022 before LP appetite closed, which is why the largest firms entered 2024 with record dry powder; our review of the biggest US venture firms covers those 2022–2024 fund closes.

What does the 2021–2023 cycle mean for founders and LPs in 2026?

The cycle shows that sector capital can halve within a year, that valuation marks lag reality by two to four quarters, and that the sector which emerges from a trough (AI in 2023, SaaS in 2009) tends to absorb a disproportionate share of the next cycle’s capital.

For founders, three practical rules emerged. First, raise when the market is open, not when you need to; companies that raised in late 2021 with 24-plus months of runway survived 2022–2023, and those that waited for better terms often took structured rounds or bridges. Second, the price of a round sets the hurdle for every later round, so a 2021-style valuation is a liability if the next round is in a 2023-style market. Third, the exit market, not the funding market, determines what equity is actually worth; 2021’s $841.5 billion of US exit value was followed by two years below $150 billion, which explains why so many 2021 unicorns were still private in 2025.

For LPs, the period is the clearest argument for vintage diversification and for scrutinising distributions. The 2020 and 2021 vintages have returned very little cash as of October 2026, and most of the paper gains in those portfolios sit in a small number of AI positions marked at 2025–2026 prices.
